This one is a little old, but I don't know that Glimmer Train has changed much over the years. I can offer Issue 36, Fall 2000. The selling point is an interview with Siri Hustvedt that is quite interesting.
If you're interested, leave a comment or send me an email with what you've got to swap and we'll work something out.
Also, I still have available Florida Review (Fall 2007) and Fugue (Summer-Fall 2006), if anyone is interested.
